Thousands of Eurostar passengers anxious to get away for Christmas battled for train places out of London today as heavy rains and freezing conditions sparked yet more travel chaos across Europe.
At least three people died in road accidents in Britain and northern Italy overnight after heavy snowfall, while frozen airports sparked further flight delays and a Ryanair jet slid off the runway in Scotland.
Meanwhile floodwaters drenched most of Venice, as a combination of wind, rain and the lagoon city's periodic tidal phenomenon saw water levels rise by 143 centimetres (56 inches), a record for the year, officials said.
In London, thousands of people left stranded by a three-day Eurostar service cancellation formed long queues at Saint Pancras International station from early in the morning in the hope of finally getting to the continent.
Tempers frayed amid confusion over who would get priority on the reduced number of trains that began running Tuesday.
"It's a nightmare," said Olivia Roman, a 28-year-old civil servant who began queuing at 6:00 am to get back to Paris after a holiday with friends in London.
Emmanuel Orejas, 41, a Belgian businessman who had been waiting there for two days with his family, also expressed frustration that he was not given priority over passengers who had not been delayed.
"We have been left without knowing anything for several days. And now they are opening the doors to all passengers, even those with tickets for Wednesday," he told AFP.
Such were the crowds that Eurostar had earlier advised passengers not yet at the station to hold off until the afternoon, but at lunchtime issued another statement saying that all its trains for the day were full.
"We will be running services tomorrow (Thursday) and we are confident that there will be sufficient seats for everyone who wants to travel before Christmas," it said.
The situation in Paris was less fraught, with seats available for everybody wishing to travel, a Eurostar spokeswoman there said, adding that about 26,000 places would be available over the day.
The normally high-speed Channel Tunnel service was brought shuddering to a halt Friday by what a British spokesman called a fall of fluffier-than-expected snow, as the cold snap brought chaos to the rest of the transport network.
Most European airports were back to normal Wednesday, a day after hundreds of flights were scrapped across western Europe, although budget airline easyJet announced dozens more cancellations at British airports due to snow.
Irish low-cost carrier Ryanair confirmed that one of its flights from Dublin carrying six crew and up to 189 passengers skidded off the runway while taxiing at Glasgow Prestwick airport. It slid onto a grass verge, but nobody was hurt.
Delays continued at Milan Malpensa airport in northern Italy after heavy snow, while bad weather was blamed for a traffic pile-up in the northwest of the country late Tuesday in which one person died and about 30 were injured.
Two women were also killed in Britain late Tuesday when the bus they were travelling in flipped over on an icy road in Cornwall, southwest England, police said. A further 47 passengers were injured in the crash.
Emergency services warned of treacherous driving conditions across much of Britain, where up to 12 million people are expected to travel for the holidays on Wednesday and Thursday, according to the motoring group AA.
Meanwhile heavy rains closed motorways in southern Spain and Portugal, where power lines were also cut by heavy winds overnight. Snowfall also forced school closures in northern Spain.
